I’m not particularly worried about myself. I’m fully vaccinated. The thing I find sadly fascinating is that so many people seem to not understand that the latest guidance on masks in airports/planes is to protect the unvaccinated from being infected by potentially infectious but asymptomatic vaccinated (or not) people. All the maskholes at the airport today either still don’t get the main point of masks over a year into this or else they don’t care about protecting people they don’t know.
